Embodiment
Should be appreciated that embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
With reference to Fig. 2, Fig. 2 is the process flow diagram of the manufacture method of LCD frame glue of the present invention.
In the present embodiment, the manufacture method of LCD frame glue may further comprise the steps:
Step S10 adds frame collagen material and evenly mixing with conducting medium, supporting fiber; Concrete, conducting medium is conductive materials such as silver or gold, the perhaps combination of these conductive materials, and the conducting resinl of prior art also is used for these conductive materials usually to be made; The supporting fiber can be the material that glass bead, glass bar or glass fibre etc. have certain support strength.Frame collagen material adopts heat curing frame glue or ultraviolet curing frame glue, and the present invention is preferably heat curing frame glue, and this heat curing frame glue is the material with sealing property that is mixed by epoxy resin, catalyzer and catalyzer solvent etc.Above-mentioned conducting medium, supporting fiber and frame collagen material are put into a container,, for example can the conducting medium in the container, supporting fiber and frame collagen material be mixed by artificial hand-held stirring rod by artificial full and uniform mixing.
Step S20 puts into the deaeration facility with the potpourri that obtains after above-mentioned the mixing and does the deaeration processing; The mode of deaeration has multiple, in the present embodiment, preferred traditional vacuum mixes deaeration, promptly adopts traditional vacuum to stir the deaeration facility to potpourri mixing deaeration, execution time can be set to 15～25 minutes, and whether the concrete execution time can be set by complete deaeration according to potpourri.Stir at traditional vacuum under the rotary action (rotation and revolution) of deaeration facility, convection current can take place in conducting medium, supporting fiber and frame collagen material in the deaeration container, thereby the three is further mixed.Because rotation and revolution are carried out in a vacuum, and convection current is to take place up and down, thereby the bubble of deaeration container bottom can float along with convective motion up and down, arrives the vacuum layer after expansion and breaks, thereby reach the deaeration effect.Judge whether the deaeration purpose reaches, can stir the deaeration facility at traditional vacuum and rotate the potpourri surface stop to observe in its deaeration container the back and get final product,, can carry out next step and be coated with picture frame and move if the no bubble in potpourri surface illustrates that then its inside do not have bubble yet.In other embodiments, also can utilize inert gas, for example said mixture can be placed in the vacuum chamber, to wherein charging into N2 (nitrogen), thereby the potpourri gas inside be discharged the potpourri deaeration.
Step S30 installs to coating machine with the potpourri branch after the deaeration; Concrete, the mixture after being mixed branch is installed to the sebific duct or the container of coating machine.
Step S40, coating machine carry out the picture frame action on the substrate of LCD, solidify the back and form LCD frame glue.Coating machine is carried out the picture frame action on array base palte, form the framework of surrounding liquid crystal, passes through processes such as UV illumination and heating again, promptly forms LCD frame glue of the present invention.Carry out the picture frame action by coating machine, can prevent that liquid crystal from exposing, aqueous vapor enters, and can obtain excellent conducting performance, have minimum effects such as spreading area.
Above-mentioned conducting medium, supporting fiber and the frame collagen material that is used for making frame glue, the shared ratio of conducting medium is chosen as 1～10%, and the shared ratio of supporting fiber is chosen as 1～10%.In the present embodiment, preferred conducting medium is a silver, accounting 2%, and preferably supporting fiber is glass fibre, accounting 1%, frame collagen material is preferably heat curing frame glue of the prior art, accounting 97%.
The frame glue of LCD of the present invention is mixed and made into by frame collagen material, conducting medium and supporting fiber, not only possesses the sealing function of traditional frame glue, also has electric action and supporting role simultaneously, can replace the frame glue and the conducting resinl of conventional liquid crystal.Further, owing to adopt traditional vacuum to stir, material is uniformly mixed, and the conduction of electric charge and dispersion are more even, and the scheme of the relative prior art of electric conductivity of embodiment of the invention frame glue is better.The manufacture method of LCD frame glue of the present invention can be improved the making flow process of LCD, overcome owing to frame glue or the residual Mura that occurs of conducting resinl or cut split bad; And, also can enhance productivity, reduce the production board and purchase and the manual operation problem of management, reduce production costs.
With reference to Fig. 3, Fig. 3 is the structural representation of the frame glue of LCD of the present invention.The present embodiment LCD comprises array base palte, color membrane substrates, is provided with the frame glue 30 of the annular of making by said method between array base palte and the color membrane substrates, and liquid crystal is injected in the annular seal space of array base palte, color membrane substrates and 30 formation of frame glue.The composition of above-mentioned frame glue mainly comprises conducting medium, supporting fiber and frame collagen material, and the shared ratio of these three kinds of compositions with make before material rate basic identical.LCD of the present invention only comprises by the prepared frame glue 30 of said method in the periphery of pixel display area, has cancelled conducting resinl of the prior art, and the function of conducting resinl is realized in the lump by frame glue 30 now originally.Frame glue 30 not only has the effect of encapsulated liquid crystals, also have electric action and supporting role simultaneously, for example, conducting medium can conduction array substrate and color membrane substrates, and the supporting fiber can support array base palte and color membrane substrates, make both have stable spacing, avoided owing to frame glue or the residual Mura that occurs of conducting resinl or cut split bad; And, improved electric conductivity.In addition, in preparation process, improved production efficiency, reduced the production board and purchase and the manual operation problem of management, reduced production costs.The manufacturing and the maintenance cost of LCD are significantly reduced, and LCD and products thereof has bigger market competition advantage.
The present invention is not limited to above embodiment, under the disclosed technology contents of above-mentioned embodiment, can also carry out various variations.Every equivalent structure transformation that utilizes instructions of the present invention and accompanying drawing content to be done, or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
